ABSTRACT:
A torque-amplifying hydraulic servo-mechanism of the kind including a rotary hydraulic motor and a hydraulic distributor, said motor being of the sliding vane type and the distributor of the "face", open center type. According to the invention, the rotor (50) of the hydraulic motor includes two diametrically opposite cylindrical surfaces (90) in contact with the stator bore and each extending over an arc equal to that between two adjacent vanes (24), and two interconnecting portions each having two flat faces (106, 108) interconnected by a cylindrical surface portion (104); and the number of vanes (94) is advantageously four times the number of said surfaces ( 90), that is eight. The servo-mechanism thus designed may be advantageously used in power steering systems for motor vehicles, and produces an output torque substantially constant irrespective of the relative position of the rotor and stator of the hydraulic motor.
